Description

Technical Field

[0001] The present invention belongs to the technical field of bearing seats, and particularly relates to a self-lubricating bearing seat and a self-lubricating method. Background Art

[0002] In industrial production and the operation of mechanical equipment, as a key component for supporting and fixing bearings, the lubrication condition of the bearing seat has a crucial impact on the performance and service life of the entire equipment. The traditional lubrication method of the bearing seat mainly relies on regular manual addition of lubricating oil.

[0003] Currently, when most bearing seats are in use, although split bearing seats are convenient for the maintenance and replacement of some components in terms of structure, in order to inject lubricating oil into the bearings during the lubrication process, it is often necessary to manually disassemble the bearing seat. This process is not only cumbersome and complex, but also requires a large amount of time and manpower. Moreover, frequent disassembly and lubrication are likely to cause wear at the connection parts, affecting the overall structural strength and stability of the bearing seat, and thus shortening the service life of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-lubricating bearing seat and a self-lubricating method to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A self-lubricating bearing seat, comprising: A mounting seat, the top of the mounting seat is connected with a bearing seat, and an installation groove is provided in the bearing seat and a bearing is connected in the installation groove; A lubrication component, the lubrication component is arranged inside the top of the bearing seat for lubricating the bearing. The lubrication component includes a lubrication groove and an oil storage sponge. The lubrication groove is arranged inside the top of the bearing seat, the oil storage sponge is arranged in the lubrication groove, the top of the oil storage sponge is connected with a pressing plate and the top of the pressing plate is connected with a pressing rod. One end of the pressing rod slides through the bearing seat and a sealing gasket is provided at the penetration of the pressing rod and the bearing seat; The bearing includes an outer ring and an inner ring. The outer ring is arranged in the installation groove and is connected with the bearing seat. The inner ring is arranged inside the outer ring and a cage is arranged between the outer ring and the inner ring.

[0006] Preferably, guide rods are connected to both sides inside the lubrication groove, and both ends of the pressing plate are slidably sleeved on the guide rods.

[0007] Preferably, an oil dripping hole is provided inside the outer ring and one end of the oil dripping hole is communicated with the lubrication groove, and an oil inlet pipe is connected inside the lubrication groove.

[0008] Preferably, one end of the oil inlet pipe penetrates through the bearing seat and is threadedly connected with a filter tip, and one end of the filter tip is threadedly connected with a sealing cover.

[0009] Preferably, a filter screen is provided inside the filter tip.

[0010] Preferably, a number of rolling grooves are annularly provided inside the cage, large balls are rotatably connected inside the rolling grooves, and the large balls are in contact with the outer ring and the inner ring.

[0011] Preferably, adjustment grooves are provided at the top and bottom of the rolling grooves inside the cage, adjustment plates are slidably connected inside the adjustment grooves, both ends of the adjustment plates are connected with sliders, and one end of the sliders is slidably connected with a chute provided inside the adjustment grooves.

[0012] Preferably, small balls are rotatably connected to the surface of the adjustment plate close to the large balls, and the small balls are in contact with the large balls.

[0013] Preferably, two groups of first springs are provided inside the adjustment grooves, and both ends of the first springs are respectively connected with the cage and the adjustment plates.

[0014] A self-lubricating method for a self-lubricating bearing seat specifically includes the following steps: S1. By introducing lubricating oil into the filter tip, the lubricating oil filtered by the filter screen flows into the lubricating groove through the oil inlet pipe; S2. Then press the pressure rod, and the pressure rod drives the pressing plate downward to squeeze the lubricating oil absorbed in the oil storage sponge; S3. The squeezed lubricating oil flows to the outside of the outer ring through the oil dripping holes; S4. When the inner ring drives the large balls to rotate, the lubricating oil dripping from the oil dripping holes at the outside of the outer ring forms an oil film between the inner ring, the large balls and the outer ring for lubrication.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By injecting lubricating oil from the filter tip, filtering it through the filter screen and flowing it into the lubricating groove, pressing the pressure rod enables the lubricating oil in the oil storage sponge to drip to the large balls through the oil dripping holes to achieve lubrication of the bearing, without the need to disassemble the entire bearing seat as in the traditional method, greatly improving the lubrication efficiency of the bearing seat.

[0016] The filter screen inside the filter tip can effectively intercept impurities in the lubricating oil, such as metal debris, dust particles, etc., avoiding impurities in the lubricating oil from entering the bearing interior, exacerbating the wear of the bearing, and affecting its accuracy and service life.

[0017] During actual operation, due to the influence of wear by various complex external forces, the distance between the large balls and the cage may change. The presence of the adjustment plate can respond to this change in a timely manner. By sliding itself inside the adjustment groove, under the action of the first spring, it ensures that the large balls always remain in a suitable position, maintaining the tightness with the two groups of small balls, effectively preventing excessive looseness between the large balls and the cage body.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a self-lubricating bearing seat as shown in Figure 1-6 and includes: A mounting seat 1, a bearing seat 2 is connected to the top of the mounting seat 1, a mounting groove 3 is provided in the bearing seat 2, and a bearing 4 is connected in the mounting groove 3; A lubricating component, which is arranged inside the top of the bearing seat 2 and is used to lubricate the bearing 4. The lubricating component includes a lubricating groove 5 and an oil storage sponge 6. The lubricating groove 5 is arranged inside the top of the bearing seat 2, the oil storage sponge 6 is arranged in the lubricating groove 5, a pressing plate 7 is connected to the top of the oil storage sponge 6, and a pressing rod 8 is connected to the top of the pressing plate 7. One end of the pressing rod 8 slides through the bearing seat 2, and a sealing gasket is provided at the penetration of the pressing rod 8 and the bearing seat 2; The bearing 4 includes an outer ring 9 and an inner ring 10. The outer ring 9 is arranged in the mounting groove 3 and is connected to the bearing seat 2. The inner ring 10 is arranged inside the outer ring 9, and a cage 11 is provided between the outer ring 9 and the inner ring 10.

[0022] On both sides inside the lubricating groove 5, there are guide rods 12 connected. The two ends of the pressing plate 7 are slidably sleeved on the guide rods 12. The guide rods 12 can provide precise guidance for the movement of the pressing plate 7, ensuring that the pressing plate 7 maintains a stable and vertical movement trajectory during the up and down movement. And a second spring 26 is sleeved on the surface of the guide rods 12. The two ends of the second spring 26 are respectively connected to the pressing plate 7 and the lubricating groove 5. When the pressing plate 7 moves downward, the second spring 26 is compressed by extrusion. And when the pressing pressure on the pressing plate 7 disappears, the second spring 26 generates an upward rebounding force by virtue of its own elasticity, applying an upward thrust to the pressing plate 7 to assist the pressing plate 7 to move upward and help it reset.

[0023] An oil dripping hole 15 is provided inside the outer ring 9, and one end of the oil dripping hole 15 is communicated with the lubricating groove 5. An oil inlet pipe 16 is connected inside the lubricating groove 5.

[0024] One end of the oil inlet pipe 16 passes through the bearing seat 2 and is threadedly connected with a filter tip 17, and one end of the filter tip 17 is threadedly connected with a sealing cover 18. By tightening the sealing cover 18, it is possible to prevent dust, impurities, etc. from entering the inside of the filter tip 17.

[0025] A filter net 19 is provided inside the filter tip 17. The filter net 19 can filter various impurities in the lubricating oil to avoid flowing into the inside of the bearing 4 and exacerbating the wear of the bearing 4. And when the filter net 19 needs to be replaced due to long-term filtering, the threadedly connected sealing cover 18 and the oil inlet pipe 16 can be loosened to replace the filter tip 17 or the filter net 19 inside the filter tip 17.

[0026] A number of rolling grooves 20 are annularly provided inside the cage 11. Large balls 25 are rollingly connected inside the rolling grooves 20. The large balls 25 are in contact with the outer ring 9 and the inner ring 10.

[0027] Adjusting grooves 21 are provided inside the cage 11 and at the top and bottom of the rolling grooves 20. Adjusting plates 22 are slidably connected inside the adjusting grooves 21. The two ends of the adjusting plates 22 are connected with sliders 13, and one end of the sliders 13 is slidably connected with a sliding groove 14 provided inside the adjusting grooves 21. When the adjusting plates 22 move, by sliding the sliders 13 in the sliding grooves 14, the moving direction of the adjusting plates 22 can be guided to enhance the stability of the movement of the adjusting plates 22.

[0028] On the surface of the adjusting plate 22 close to the large balls 25, small balls 23 are rollingly connected and the small balls 23 are in contact with the large balls 25. Two groups of first springs 24 are provided inside the adjusting grooves 21, and the two ends of the first springs 24 are respectively connected to the cage 11 and the adjusting plates 22. Under the elastic force of the first springs 24, the small balls 23 can always maintain contact with the large balls 25.

[0029] A self-lubricating method for a self-lubricating bearing housing, specifically including the following steps: S1. By introducing lubricating oil into the filter tip 17, the lubricating oil filtered by the filter screen 19 flows into the lubricating groove 5 through the oil inlet pipe 16; S2. Then press the pressing rod 8, and the pressing rod 8 drives the pressing plate 7 downward to squeeze the lubricating oil absorbed in the oil storage sponge 6; S3. The squeezed lubricating oil flows into the outer ring 9 through the oil dripping hole 15; S4. When the inner ring 10 drives the large ball 25 to rotate, the lubricating oil dripping from the oil dripping hole 15 in the outer ring 9 forms an oil film between the inner ring 10, the large ball 25 and the outer ring 9 for lubrication.

[0030] For this self-lubricating bearing housing and self-lubricating method, when lubricating the bearing housing 2, loosen and open the sealing cover 18, slowly pour the lubricating oil into the filter tip 17. The filter screen 19 in the filter tip 17 can effectively intercept various impurities in the lubricating oil. The filtered lubricating oil flows along the oil inlet pipe 16 and, relying on gravity and its own fluidity, flows into the lubricating groove 5. The oil storage sponge 6 placed inside the lubricating groove 5 has good water absorption and oil storage capacity. It will quickly absorb the flowing lubricating oil and store it. Then the operator manually presses the pressing rod 8. One end of the pressing rod 8 is firmly connected to the pressing plate 7. During the pressing process, the pressing rod 8 drives the pressing plate 7 to move downward along the guide rods 12 on both sides inside the lubricating groove 5. The guide rods 12 can play an accurate guiding role to ensure that the pressing plate 7 remains stable during the movement and prevent deviation, so as to evenly squeeze the oil storage sponge 6. As the pressing plate 7 is pressed down, the oil storage sponge 6 is subjected to an increasing pressure, and the lubricating oil stored inside it is extruded. These extruded lubricating oils flow into the inside of the outer ring 9 through the oil dripping holes 15. When the inner ring 10 drives the large ball 25 to start rotating under the action of an external force, the lubricating oil dripping from the oil dripping hole 15 starts to play a role. Since the large ball 25 is in close contact with the inner ring 10 and the outer ring 9 and the large ball 25 is in a rotating state, under the combined action of friction and centrifugal force, the lubricating oil quickly spreads between the inner ring 10, the large ball 25 and the outer ring 9 to form an oil film with good lubrication performance, thereby realizing the self-lubrication of the bearing housing 2 and greatly reducing the friction coefficient of the bearing 4 inside the bearing housing 2.

[0031] The annularly distributed rolling grooves 20 in the cage 11 provide an accurate rolling track for the large ball bearings 25, ensuring the stability of the large ball bearings 25 during rotation. In the adjusting grooves 21 located at the top and bottom of the rolling grooves 20, slidable adjusting plates 22 are installed. The adjusting plates 22 are connected to the cage 11 through the first springs 24 and are installed in the adjusting grooves 21 and can slide along the sliding grooves 14. When wear occurs during long-term use, resulting in an increase in the distance between the large ball bearings 25 and the cage 11, the compressed first springs 24 can push the adjusting plates 22 to adjust the positions of the small ball bearings 23, enabling the small ball bearings 23 to closely adhere to the large ball bearings 25, maintaining an appropriate tightness between the small ball bearings 23 and the large ball bearings 25, ensuring smooth operation, and avoiding problems such as noise and unsmooth rotation caused by the collision between the large ball bearings 25 and the cage 11 when the looseness due to wear between the large ball bearings 25 and the cage 11 is excessive.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
